It's time to replace the chassis battery in our Windsport 27K. I've searched the forum and can't seem to find a list of what to do and what NOT to do! For starters I plan to disconnect the shore power, switch the coach to Store mode, and open the 100 amp breaker on the coach batteries. I will then disconnect the negative/ground cable from the chassis battery, followed by the positive cable. After physically switching batteries I plan to install the positive cable first and then the ground, After which I will activate the coach batteries and switch out of Store mode.



Did I miss anything or am I doing something wrong??? All advice will be appreciated! I'm hoping the hardest part of this job is going to be getting the old battery out and the new one in place.
